commit 97f3efb64323beb0690576e9d74e94998ad6e82a upstream

The hyper-v transparent bonding should have used master_dev_link.
The netvsc device should look like a master bond device not
like the upper side of a tunnel.

This makes the semantics the same so that userspace applications
looking at network devices see the correct master relationshipship.

Fixes: 0c195567a8f6 ("netvsc: transparent VF management")
